Our most ergonomic and comfortable chair, and it just so happens to be eco-friendly, too. Made with a high impact nylon base, the breathable mesh keeps you cool, providing better air circulation between the chair and your body. Excellent lumbar support contributes to a healthy posture and increased comfort, especially when paired with extensive adjustability. With pneumatic height adjustment, your low-back, glutes, and thighs will be balanced and properly supported. The seat slider lets you adjust the seat back and forth, protecting the pressure points behind your knees, while maintaining optimal blood flow to your feet. The synchro-tilt mechanism allows you to lean back in your chair and with tilt-lock and tension control, you decide how much. The 3-way adjustable armrest will ensure your arms are happy, too. This green-certified Mesh Back Chair completely adjusts to you, and because it is made of recycled and recyclable materials, it's good for you and the environment. And that's something we can all feel positive about.
